Abstract

The invention relates to the technical field of communication testing, in particular to a device for testing the performance of an optical module receiving end, including a bit error rate tester, which includes a signal sending module, a microchip, an electrical signal analysis module, and an electrical signal receiving module. The signal sending module is connected to an optical attenuator through an optical cable, the optical attenuator is electrically connected to a computer, the optical attenuator is connected to a spectrometer through an optical cable, the spectrometer is connected to an optical module and an optical power meter through an optical cable, and a receiver is installed in the optical module and an optical signal output module, the optical signal output module is connected with an oscilloscope through an optical cable, and the oscilloscope includes an optical signal receiving module, a converter, a processor, an electrical signal sending module, a signal display module and a display. The advantage of the present invention is that it can detect the loss and error of the optical signal in the testing process, thereby accurately judging the signal receiving capability of the optical module.

Description

technical field [0001] The invention relates to the technical field of communication testing, in particular to a performance testing device for an optical module receiving end. Background technique [0002] The optical module is composed of optoelectronic devices, functional circuits and optical interfaces. The optoelectronic devices include two parts: transmitting and receiving. Simply put, the function of the optical module is photoelectric conversion. The transmitting end converts electrical signals into optical signals. After transmission through optical fibers, receiving The end converts the optical signal into an electrical signal, and the transmitting part is: input an electrical signal with a certain code rate and process it through an internal driver chip to drive a semiconductor laser (LD) or a light-emitting diode (LED) to emit a modulated optical signal at a corresponding rate. There is an automatic optical power control circuit inside to keep the output optical ...
